That was by far the best Naruto manga I have ever read. Everything about this was great 5/5.
If you dont like how sasuke "just" changed his mind, you forget this sh*ts been going on FOREVER. He been manipulated his brother, Oro,and by tobi. Finally has all the information laid out to him for once. so being that this is the first time he's actually able to make an educated choice for himself, and makes the right one, it makes up for all the past times he hadn't.
For anyone who bashes Oro choice, I'd say you have no clue about what he's been going through. Hes been out for quite some time, and like he said, he sat and watched how his previous ideals would pan out with kabuto. not to mention his world will be just as over as everyone else if madara's wins. so it not crazy that he would agree to follow sasuke if nothing else than for curiosity and survival. Epiphanies aren't long winded, they happen and you change forever.
for the people who bash karin, you are preety naive. plenty of women have dependent personalities, and it wouldnt matter how many time the man they "love" hurts them, they will keep running back. You want imaginary characters to be perfect bc you like to imagine that's how you'd act in their situations, but that's not real. Id rather have flawed characters that bring realism to the story, than to have everyone be super self realized and always making the right choices.
Again this chapter is best i've read.
